Pemetrexed in the Treatment of Leptomeningeal Metastasis in Patients With EGFR-mutant Lung Cancer.

Clin Lung Cancer 2019 Mar 29. Epub 2019 Mar 29.

Department of Internal Medicine, Seoul National University Hospital, Seoul, Korea; Seoul National University Cancer Research Institute, Seoul National University College of Medicine, Seoul, Korea.

Introduction: Leptomeningeal metastasis (LM), still an area of unmet need, has frequently been observed in patients with EGFR-mutant non-small-cell lung cancer (NSCLC). Because the antitumor efficacy of systemic cytotoxic agents against LM is unclear, we explored the role of pemetrexed in the treatment of patients with LM from EGFR-mutant NSCLC.

Patients And Methods: We retrospectively reviewed the medical records of patients with LM from EGFR-mutant NSCLC treated between 2006 and 2016. Read More

Osimertinib in the treatment of leptomeningeal disease in T790M-negative, epidermal growth factor receptor-mutated non-small cell lung cancer: a case report.

Chin Clin Oncol 2019 Mar 4. Epub 2019 Mar 4.

Department of Medical Oncology, St George Hospital, Sydney, Australia; Department of Medical Oncology, The Sutherland Hospital, Sydney, Australia.

Leptomeningeal carcinomatosis (LMC) is a terminal event in advanced cancer, its incidence in epidermal growth factor receptor (EGFR)-mutant non-small cell lung cancer (NSCLC) is increasing due to recent advances in systemic therapy and prolongation of survival. Osimertinib is a third generation EGFR-tyrosine kinase inhibitor (TKI) with preclinical and early clinical studies showing activity against LMC resistant to previous TKI treatments and acquired T790M mutation. We report a case of osimertinib in the treatment of LMC in a T790M-negative, EGFR-mutated NSCLC with significant clinical benefit and no toxicity. Read More

Next-generation Epidermal Growth Factor Receptor Tyrosine Kinase Inhibitors for Leptomeningeal Carcinomatosis: Review of 2 Cases.

Neurologist 2019 Mar;24(2):59-61

Department of Neurology, Mayo Clinic, Scottsdale, AZ.

Introduction: Epidermal growth factor receptor (EGFR) mutation status is strongly correlated with leptomeningeal carcinomatosis in non-small cell lung cancer. Historically, patients were treated with radiotherapy, intrathecal chemotherapy or first-generation EGFR tyrosine kinase inhibitors (TKIs); however, most would eventually develop resistance and disease progression. Therefore, recent interest has sparked in investigating next-generation EGFR-TKI monotherapy. Read More

Success of Crizotinib Combined with Whole-Brain Radiotherapy for Brain Metastases in a Patient with Anaplastic Lymphoma Kinase Rearrangement-Positive Non-Small-Cell Lung Cancer.

Case Rep Oncol 2018 Sep-Dec;11(3):777-783. Epub 2018 Nov 29.

Department of Oncology, Pharmaceutical Care and Sciences, Okayama University, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama, Japan.

Although crizotinib shows marked antitumor activity in anaplastic lymphoma kinase (ALK) rearrangement-positive non-small-cell lung cancer (NSCLC) patients, all treated patients ultimately develop resistance to this drug. Isolated central nervous system failure without progression at extracranial sites is a common progression pattern in ALK rearrangement-positive NSCLC patients treated with crizotinib. Here, we report the success of crizotinib combined with whole-brain radiotherapy in an ALK rearrangement-positive NSCLC patient who developed leptomeningeal carcinomatosis and progression of multiple brain metastases.

Diagnostic Approach to Chronic Meningitis.

Neurol Clin 2018 Nov 20;36(4):831-849. Epub 2018 Sep 20.

Department of Neurology, Geisinger Commonwealth School of Medicine, Geisinger Medical Center, 100 North Academy Avenue, Danville, PA 17822, USA.

Chronic meningitis is defined as cerebrospinal fluid pleocytosis that persists for at least 4 weeks without spontaneous resolution. The differential diagnosis of chronic meningitis is broad, encompassing 4 main categories, including infectious, autoimmune, neoplastic, and idiopathic. Up to one-third of cases have no discernible cause, making chronic meningitis a diagnostic dilemma for many clinicians. Read More

Management of breast cancer brain metastases.

Chin Clin Oncol 2018 Jun;7(3):30

Section of Neurosurgery, Niigata Cancer Center Hospital, Niigata, Japan.

Brain metastases are usual in breast cancer with poor prognosis and few available therapeutic options. The efficacy of epidermal growth factor receptor-tyrosine kinase inhibitors (EGFR-TKIs) against brain metastases from EGFR mutation-positive non-small cell lung cancer (NSCLC) showed promising antitumor activity, on the other hand, the main treatment of breast cancer brain metastases (BCBMs) is only local therapy such as surgery or radiotherapy. The goal of treatment includes stabilizing or improving neurological function and palliating neurological symptom. Read More
